ATTACHMENT FOB BOOXXEEPIN'G4 HAUHENES. I

Application led November 17, 1925. Serial lo; 09,721.

To all whoml it may concern lle it known that I, lVAxJiuu MARQUIS, acitizen of the United States, residing at Cuero, in the county of DelVitt and State of Texas, have invented a new and usefulv Utachment forBookkeeping Mac-lunes, of'

which the following is a specification.

This invention relates to an attachment for bookkeeping machines orposting machines, one of the objects being to provide a means wherebythe printed balance to be brought forward will be magnified, when thecarriage is in position for this procedure, so that the operator candecipher the same quickly without straining the eyes. c

A further object is to provide an adjustable attachment of thischaracter which can be applied readily to a standard type of machine andwill enable the operator to do more accurate work and relieve him ofmuch 'of the eye strain to which Ihe is subjected where an attachment'ofthis type is not employed.

A further object is to provide an attachment which can be applied tomachines of different widths and which is simple and neat inconstruction and cheap to manufacture.

A still further object is to provide an attachment the position of whichcan be varied so as to focus the magnifying glass to suit the vision ofthe operator.

With the foregoing and other objects in view which will appearas thedescription proceeds, the inventionresides in the combination andarrangement of parts and in' the details of construction hereindescribed yand claimed, it being understood that Figure 3 is an enlargedsection-on line 3-3 Figure 1.

Referring to the figures by characters of Areference 1 designates aportion of a bookkeepmg machine of a standard make, the same beingprovided with a carriage 2 on which is arranged a sheet 3 located asshown in Figure 1 when a balance must be picked up before proceeding.The attachment constituting the present invention includes a tube openat its ends and provided, at one end, with a fixed jaw 5. Slidablymounted on the other end portion of the tube is a sleeve 6 carrying ajaw 7. A nut 8 is mounted on the tube close to the sleeve 6 and it willbe apparent that the tube can be attached readily to the casing of thebookkeeping machine 1 simply by placing the jaws 5 and 7 at oppositesides of the casing and then adjusting the nut 8 so as to clamp the twojaws on the casing. A rod 9 is ad- Justable longitudinally within oneend portion of the tube and is adapted to be held in any desiredpositions by a setl screw 10 carried yby the tube. This rod has an L-shaped arm 11 extending therefrom, the end portion being arranged withina sleeve 12 which can'be secured thereto in any position to which it isadjusted, by means of a set screw 13. An extension 14 is provided 'onthe sleeve and is formed with a longitudinal bore 15 extended at rightangles to the longitudinal axis of the sleeve 12. Bore 15 has a setscrew 16 adapted to bind upon a stem 17 to which are pivotally connectedears 18 extending from a frame 19. `A binding screw 20 constitutes theconnection between the ears 18 andthe stem 17 and by tightening thisscrew frame 19 can be supported at any desired angle relative to thestem 17. `-This frame 19 holds a magnifying lens 21 which issubstantiallyrectangular.

The attachment herein described is `adapted to be fastened to a standardbookproper position to pick up the balancebefore proceeding.

Itwill be obvious that this attachment can he adapted for use withditl`trtnt'. types of bookkeeping or vostng machines and, hy providingthe relatively adjustable jaws 7 and 5, said'nttathuwnt' van lw fastenedquirkly to'nuu-hiues ot' ditl'ervut widths.
